Oil well-fire containment device

ABSTRACT

An apparatus for reaming and tapping an oil well casing and sealing the casing against escaping oil is disclosed. The apparatus comprises a self-tapping sleeve assembly the functions of which are to provide an internal seal to an oil well casing and cause cessation of escaping oil. In the process of capping the well, burning oil, if present, is simultaneously extinguished. Utilizing the present invention, there is no necessity of providing water to cool the wellhead prior to capping, no need to excavate reservoirs to contain oil after fire extinguishment, nor is there need to bring a crew to the well head until the well is capped and flow stopped.
